Ice Age

This energetic guide to Earth's ice ages pairs photographs, digital artwork, and three pop-up spreads with information about life in these prehistoric periods, for animals and early humans alike. Details about extinct species like the kangaroo-lion and four-tusked gomphotheres sit alongside facts about animals who survived to the present, such as polar bears; several significant fossil finds are also discussed. With a compelling visual presentation and a closing time line, it's an exciting glimpse at a vanished era. Ages 8–up. (Oct.)
